[QUOTE="Bruce1300, post: 1255530, member: 88459"] Based on the responses from jmgrif and Fred W, I'm feeling more comfortable about my TBS. This bike being my first "high tech" modern machine, I was afraid that not being at a particular throttle body vacumn rate might have an adverse effect on the air/fuel mixture or something else that might upset some kind of computerized sensor. On older carburated bikes I never thought about vacumn pressure. It was just a mechanical adjustment between carbs to bring them together at an equal vacumn level which just meant adjusting the mechanical carb throttle levers to speed up or slow down the carbs until they were the same. Now that I know cyl 3 is bottomed out and is as high as it will go, future TBS will be a piece of cake; just confirm that cyl 3 is bottomed out and adjust the other three to match. Thanks for your help, Bruce in Kingsport TN [/QUOTE]
